2 Claims.

This invention relates to seed planters and especially to corn planters.

One of its objects is to provide an accurate corn planting means that isautomatic in operation.

Another object is to provide a corn planter that electrically controlsthe seed feeding to the planter, from a hopper.

Another object .is to provide a means for accumulating seed in aposition to be readily dropped in a furrow.

Another object is to provide a means for electrically accumulating andreleasing the seed.

l'he manner of accomplishment of these and other objects, which willappear hereinafter,

will become apparent from a reading of the specification, taken inconnection with the accompanying drawings, in which Figure 1 is a topplan view of the planter,

Figure 2 is a section taken on line 2-2 of Figure 1,

Figure 3 is a section taken on line 3-3 of Figure 2,

Figure 4 illustrates the switch actuating means,

Figure 5 is a detail view illustrating the support means for the switchactuating means,

Figure 6 is a sectional view, taken on the line 5-6 of Figure 2,

Figure 7 is a diagrammatic view of the electrical actuating means and,

Figure 8 is a detail view of the switch.

Referring now to the drawings, the wheels Iii.

and H located at the rear end of the planter are positioned on the axle52 which supports the side beams 23 and [4, which are connected at theirrear ends by the cross member I5. Transverse of and at the forward endsof the beams l3 and M are the cross members It and H which support attheir center the tractor hitch IS.

The outer ends of the transverse members it and H are connected by themembers l9 and 25. Intermediate these members are arranged the seedhoppers 2| and 22 and by reference to Figure 2 the operation of the seeddispensing means will be clearly understood. Below the hopper anddepending from the frame is a hollow shoe supporting casing Zl which issupported at its rear end and front end 28 and 29, respectively, by thecross members It and ll, respectively. Casing 2? may be made in onepiece or in sections, depending on the most economical and convenientmanner of making it. A guard member 35 forms the outer portion of thecasing 21 and forwardly thereof is an outlet tube 3| leading from thehopper 2i and below said outlet tube is a tubular delivery conduit 32mounted intermediate its ends for pivotal movement on a pivot 33, thetop of the conduit being closed in one position, as by a flange 3 saidflange being attached to, or made a part of the outlet tube 3!, whilethe conduit 32 also has integral therewith at its top and forward sidean arcuate flange 31. Flange 31 forms a closure for outlet tube 3! inthe position of the device in which flange 34 closes the upper end ofthe conduit 32. In this position also the lower end of conduit 32 isclosed by an arcuate flange 3? comprising an integral part of a shoe 69,to be more fully described hereinafter.

The closure 3'! acts as a valve to shut ofi the flow of seed from thehopper at the lower end of the outlet 3!. The sections 35 and 35 of theconduit 32 are operated as a unit by an electrical arrangement whichwill be described hereinafter.

A cross shaft 5! is supported at its ends by the apron 32 of the frame2'! through means of the retaining elements 53. Attached, intermediatethe ends of the rod, is a crankarm it the free end of which is pivotedto the outer end of the pusher d5 of the solenoid at which may besuspended from the cross member il. Fastened to the ends of the shaft 4!are crankarms 41 having pivoted at their lower ends the links 58, whichare attached at 49 to the section 35 of the conduit 32.

Positioned below the rearward end of the link it is a rod 50 which isheld in a socket 5!, Figure 6,

attached to the apron 52, one end of a spring 52 being seated around thesocket, the other end of said rod being positioned in a socket 53 whichis attached to a check valve 54 and the corresponding end of said springacting to pull said flap valve toward the section 36 of the conduit.

On the outer sides of the members E9 and 2B, Figure l, are located theguide rollers, arranged in pairs, 55, 55, 5! and 53, respectively,rotatably mounted on suitable shafts. The rollers are arranged to havepassed therebetween a line 55, preferably wire, having equally spacedbuttons thereon which while passing under a switch Bl will bear againstthe lower arm 62 of the pivoted member 63 thus causing the point 64 tocontact Operation The operation of the planter is as follows: Seed fromthe hopper will feed into outlet 31 and at the lower end thereof theseed will be retained by the closure 31 and when this closure is openedby means of the solenoid 45, and the intermediate parts, alreadydescribed, the seed will be deposited in a reservoir below said outlet.The same action that closes the outlet 3! will move the conduit 32 to aposition for reception of the seed through the valve 54. The seed willthen be deposited in said conduit and be allowed to pass to a furrowthrough the bottom opening thereof.

The shoe or furrow opener 59 is of any conventional type and may beadjustably arranged at its forward end by means of a link arrangement70, its rear end being pivoted in any convenient manner.

While I have illustrated two seed hoppers, any number of same may beutilized.

There has been described and illustrated the preferred embodiment of theinvention but various changes and modifications may be made within thescope of the invention whereby, any type of seed may be planted.

What I claim is:

l. A seed planter comprising a hopper, a discharge tube communicatingwith and depending from said hopper, a furrow formin shoe below saidhopper, a hollow shoe support depending from beneath said hopper aboutsaid tube, a tubular delivery conduit below said tube, means rockablysupporting said delivery conduit, a valve plate carried by said deliveryconduit and adapted in one position of the latter to close saiddischarge tube, a closure plate carried by said shoe adapted. to closethe lower end of said delivery conduit at the time that said valve plateis in closed position, an arcuate flange carried by said discharge tubefor closing the upper end of said delivery conduit when said valve plateand said closure plate are in closed position, a spring normally rockingsaid delivery conduit to valve closing position, a check valve pivotallycarried by said delivery conduit, an operating rod pivotally carried bysaid shoe support and connected to said check valve for closing thelatter when said delivery conduit is in the valve opening position, andmeans for rocking said delivery conduit to valve opening position.

2. A seed planter comprising a hopper, a discharge tube communicatingwith and depending from said hopper, a furrow forming shoe below saidhopper, a hollow shoe support depending from beneath said hopper aboutsaid tube, a tubular delivery conduit below said tube, mounting meansconnected to said delivery conduit intermediate the length thereof forrockably supporting said delivery conduit in said shoe support, a valve;plate carried by said; delivery conduit and adapted in one position ofthe latter to close said discharge tube, a closure plate carried by saidshoe adapted to close the lower end of said delivery conduit at the timethat said valve plate is in closed position, an arcuate flange carriedby said dischange tube for closing the upper end of said deliveryconduit when said valve plate and said closure plate are in closedposition, an opening formed in the side wall of said delivery conduit, acheck valve pivotally carried by said delivery conduit above saidmounting means, an operating rod extending through said opening andpivotally connected at the opposite ends thereof to said shoe supportand said check valve and adapted to dispose said check valve in seedcatching position when said delivery conduit is in valve openingposition, a spring normally rocking said delivery conduit to valveclosing position, and means for rocking said delivery conduit to valveopening position,
